Be it known that I, C AnKsoN Disnnoo','a cit aen the United States, residing at New. Rochelle, in'the county ofWVestchescertain new and useful Improvements in Renewable Insulations for Rail Joints, of

vhich the following isa specificationu having readily renewable and replaceable parts, which facilitate the renewals-3nd; re-

placement of \vorneout sect-ions ofinsulation without disturbing good and unwornsections which "are still serviceable.

The present invention primarily is in ,tended to meet the requirement i": replacing the same time the WOIIl portion of the head of the insulatingend post'and the'adr L7 ,but at the same timethe excessive'wear on the of insulation time to time.

; jiccordingly, means need only be replaoedfrom HO i i I ha ve been provided for renewing the head-sections' of insulation subjected to the greatestsvear, but such means have not contemplated the renewal of or, tho -v:orn head portions ot theendpost in sulation between the meeting-ends i of the rails In that'connection, it has been observed that when the head section 0t insu-- lation under the rail headsat'or 'ad acent 4!) head portionot the 'insula usually the n.

e end post has also Worn out. Therefore, it IS head section for newable endpost head section.-- a

- Consequently, the present invention' provides for renewing apart of the insulating 0 end post at the time of renewing the wornout portions of the joint bar insulation at or adjacent the 'meetinguends of the-rails in the joint' 7 ter and State oflleiv. York, have invented.

This inventionrelates to that type of sec-a tion'al insulation for insulated ra1l joints .lacent headsections of insulation under the a meeting ends" veiitionl insulation is limited to comparatively small areas so that a relatlvely small amount parts throughout the several the meeting ends of the railswears out, the

inobject of the progosed -improivement to provide a renewable unit of-insula- .tion which includes not only a, renewable; the joint'barybut alsofl-a re- I acentjthe joint. v

Thisis ofjpractical inipo replacement thus effecting a great saving in rtance since 7 the joints that wearout their insulation most maintenance purposes and repai With these and other objects invieiv ivhich will more readilyappear as the nature of the inventionis better understood, the sameconsists in the novel construction, combination The essential features oi the combinations clalmed herein are necessar ly susceptible of ings, in which, e igure lis e a side elevation joint with the joint bar removed insulation unitembodying the Figure 2 is a detail perspectiv proved, insulation unit shown in Figure change Without departing fron'r the; inren tion, but a preferred and pract cal embodi ment is shownfin the accompanyingdraw of therail exposing an present in e'oiethe .F

The renewable insulation unit contenr includes a and an end post head section of insulation designated bythenumeral 2. These sections of insulation areformed of hard fiber or other in sulation material suitable for: the purpose,

andare designed to be associat conventional :or other joint insulation 3,, which'isnot"sub]ected to very great wear" ed with the and remains in service for a much greater period of time than the insulation at and" meeting'ends of the rails in the, I 105- in Figures 1 and '2 ofthe drawings: each bar sists of a short length of fiber of a curved of the joint frequently are generally installed in busy,

track which allows verjz limi ed time ior 5 figures of the a r whead section lsof insulation preferablycon- Furthermore, another'ob ect of the 1nvention is to provide a renewable insulation unit 'thereo'i": and proglecting lute'r'illy' V as to permit the [i 7 mil surfaces. Tliie is shown in Figui'e 01 r the direwlngs in connection with the form those '1.
